BMW Z4 M Sport Package released

BMW is to debut the M Sport Package for the Z4 at the Detroit Auto Show Back in September we brought you some pictures of what at first glance appeared to be a BMW Z4M, despite BMW making it clear that they are not going to build an M car this time round. But it actually turned out to be a Z4 with M Sport Package zapping round the Nurburgring looking, to all intents and purposes, like a new hot Z4. Almost three months on BMW has finally got round to revealing the M Sport Package for the Z4 which will – just like the BMW Z4 sDrive35is we reported on yesterday – debut at the Detroit Motor Show in  January 2010.

Brabus tunes Mercedes-Benz CLA 45 AMG to 394 hp

It was only a matter of time before German tuning house Brabus looked at the Mercedes-Benz CLA 45 AMG and said: nahh, it's just not powerful enough. Recall that the base CLA 45 AMG already produces 355-hp and 332 lb-ft of torque courtesy of its modestly sized 2.0-liter turbocharged inline-four (an impressive feat by itself, yielding the highest output of any production four-cylinder engine), which gives it the ability to get to 60 mph in just 4.4 seconds. Given its $48,375 price tag for stateside 4Matic all-wheel drive version, many would call that a bargain for the performance stats provided.

Mercedes C-class Coupe (2011) first pictures

Mercedes is expanding the C-class range further with this new C-class Coupe. Due to be shown at the 2011 Geneva motor show, the new two-door C apes the larger CLS in style, yet is tipped to cost from £30,000 when sales start in June 2011. The C-class Coupe essentially slots in where the CLK left off.
